Lindsay Lohan attends Alcoholics Anonymous meetings every day.

The 27-year-old actress, who admitted to ''screwing up'' and drinking since leaving rehab last summer when confronted by her life coach AJ Johnson on the latest episode of her reality TV show on Sunday night (06.04.14), is determined to stay sober and hasn't touched alcohol since her slip-up.

A source told E! News: ''She has been really good lately.''

The troubled star, who has been to rehab six times, attended a Miley Cyrus concert in Brooklyn, New York on Saturday (05.04.14), but the insider insisted she didn't drink and went home right after the show.

On Sunday's episode of 'Lindsay,' AJ confronted her after her mother Dina Lohan claimed they had shared a glass a of wine, and she then found a bottle in the troubled star's apartment.

But she was furious to be confronted on camera and initially denied relapsing before later admitting to ''screwing up''.

The 'Machete' star - who fled to Los Angeles for a week and failed to contact AJ as planned - said: ''I rushed into a relationship .. and I jumped right into a relationship where we weren't on the same page.

''I wasn't considering the fact that the person I was seeing does drink and yeah. ... I had some wine.

''It's OK to admit it.... It's really scary. ... It took me a bit to realise, but then I thought, why am I holding this in?

''Yeah, f**k it, I screwed up and that's OK.''
